Abstract

the invention discloses a novel hob auxiliary type drag suction dredger drag head. The drag head comprises a drag head cover, a reduction gearbox, a coupler I, a coupler II, an underwater motor, a rotating shaft, a hob and a drag tooth, wherein the reduction gearbox, a coupler I, a coupler II and the underwater motor are located on the side of the drag head cover, the rotating shaft, the hob andthe drag tooth are located in the drag head cover, an output shaft of the underwater motor is connected with an input shaft of the reduction gearbox through the coupler I, an output shaft of the reduction gearbox is connected with the rotating shaft through the coupler II, the rotating shaft drives the hob to rotate for cutting, the drag tooth is located at the front end of the drag head, and thehob is located at the rear end of the drag tooth. According to the novel hob auxiliary type drag suction dredger drag head, the novel hob is adopted to assist the drag head to break rocks, so that theproblem of insufficient rock breaking capability of a traditional drag head is overcome, the efficiency of cutting the rocks by the drag suction dredger is improved, and the application range of thedrag suction dredger is enlarged.

Description

technical field [0001] The invention relates to a novel hob-assisted drag suction dredger head, which belongs to the technical field of dredging engineering. Background technique [0002] With the rapid development of my country's shipping industry and the vigorous development of infrastructure projects such as ports and waterways, the domestic demand for dredging ships is increasing. Trailing suction dredger is the most commonly used dredging ship in dredging projects. It has strong wind and wave resistance, little interference to shipping, large dredging depth, and unlimited transportation distance. It is suitable for land reclamation and large ports for deep water and long-distance operations. Waterway construction and maintenance projects. With the gradual widening and deepening of port channels at home and abroad, dredging projects for hard clay, cemented sand and even rocky substrates are increasing. For rocks and soils with a uniaxial saturated compressive strength g...
